Microplastics in Sediment (Deep Lake)

Sediment cores from deep lake bottoms are collected by Environment and Climate Change Canada (ECCC) using a box corer deployed from a ship. Sediment core samples in shallower depths (<9 m) are collected using a glew gravity corer and fishing boat.

Natalie Chris

Microplastics in Sediment (River/Pond)

We collect sediment from river and pond bottoms using a petite ponar grab, metal trowel and pan, and glass jars.

Kelly Owen

Micro- and Macroplastics along Shorelines

We search for plastic debris along shorelines using sieves and our hands and place the particles in paper bags.

Microplastics in Biota

Mussels are identified using a viewer on the surface of the water. Fish are caught by local northern communities and their stomachs are sent to us for processing.
